Creating Perfect Mashed Potatoes and Gravy is a delightful experience. Follow these simple steps to achieve the best results:

For the Mashed Potatoes:

1. Prepare the Potatoes: Peel the russet potatoes and cut them into evenly sized chunks.
2. Boil the Potatoes: Place the potato chunks in a large pot of cold salted water. Bring to a boil and cook until tender, about 15-20 minutes.
3. Drain the Potatoes: Once cooked, drain the potatoes in a colander. Allow them to steam dry for a couple of minutes to remove excess moisture.
4. Mash the Potatoes: In a large mixing bowl, add the drained potatoes and begin mashing them until smooth.
5. Add the Creaminess: Gradually add in the whole milk and unsalted butter. Mix until fully combined and creamy. Season with salt and freshly ground black pepper to taste.
6. Serve the Mashed Potatoes: Transfer the mashed potatoes to your serving dish, and keep warm while preparing the gravy.

For the Gravy:

1. Prepare the Roux: In a saucepan over medium heat, melt ¼ cup of unsalted butter until fully melted.
2. Add Flour: Stir in the all-purpose flour, whisking constantly for about 2 minutes until it turns golden brown.
3. Add Broth Gradually: Slowly whisk in the chicken or vegetable broth, stirring continuously to prevent lumps from forming.
4. Season the Gravy: Add the soy sauce and Worcestershire sauce, then simmer the gravy for 3-5 minutes until it thickens to your desired consistency.
5. Adjust Seasoning: Taste the gravy and adjust the seasoning with salt and pepper.
6. Serve the Gravy: Pour the warm gravy over the mashed potatoes in the serving dish.
